CONTAINER LID.

Application filed January 16, 1922. Serial No. 529,647.

'17 Yo @ZZ @07mm t may concern.'

Ee it known that l, FREDERICK Gwnn, a citizen of the United States, residing at Detroit, in the county ot la-yne and State e olZ Michigan, have invented certain new and useful `improvements in Container Lids, of which the following is a specification.

rlhis invention relates to a liquid-tight lid for containers. The lid is especially designed for use on washing machines where the rotating or oscillating drum acts alsoas a container for the washing iuid. lt is desirable in a washing machine to provide 'a lid that can be quickly clamped down int-o liquid-tight relation with the container and yet which can be completely reinoved out of the way when it. is desired to charge the container. Furthermore, it is highly necessary that a lid should be provided which can be `adjusted to take up wear, warping or distortion of the parts so that in the course of usage the lid will not leak or lose its usefulness because the parts become slightly distorted. The objects outlined are accomplished by niy improved lid construction, which will be more fully described in detail'.

a designates a drum for containing a washing vfluid and for containing the clothes to be washed. This drum is provided with an elliptical opening in its one side for charging the saine. This elliptical opening is surrounded by an angle iron riin Z) riveted ontol'he drum. This affords not only a reinforcement for the opening butit also provides an upstanding flange adapted to drive into the distortable packing ring c, which is preferably cork. This packing ring` is carried on the under side or" the lid or cover CZ.

The cover is preferably a casting of sorne light ineta'l such. as aluminum alloy. lt is elliptical in shape with a tinned-out and turned-over outer flange c which Jliornis a seat for the packing ring c. This lid curves el is a section taken on the line 4 -4 along the ininor axis of the ellipse to accord with the radius ot the cylinder. Running along` the inaj or axis of the ellipse is a heavy rib or lever which continues on beyond the end of the cover 'to form an ear e. At the opposite end of the cover the rib or lever projects be-yond the body of the cover to form the bifucated ear f. The ear e is drilled and tapped and into this can be run a cap screw h on which is a lock nut i, to hold the cap screw in any position of adjustinent. 0n one end of the charging opening is secured a heavy iron clip j, preferably by rivets, to the rini flange so as not to place any of the load upon the thin sheet metal that i'orrns the body of the drum. At the opposite end o't' the elliptical charging open ing is a pair of clips 7c, k which form journal bearings for the l`-bolt m which has a wing nut n on its end.

F rom the forego-ing description it will be easily understood how the lid can be quickly clamped in place. @ne simply has to push the cap screw end of the lever or rib under the clip and the T-bolt clamp is then swung up into the biturcated end of the lever at thel opposite nd and the wing nut turned down to clamp the lid in place. This action is a peculiarV one. The lid becomes in effect a lever. rThe main stresses, of course, are taken by thel thick reinforcing rib.' The point oi: Contact oi the cap screw with the clip or fulcrurn support becornes the fulcruni of the lever and the load is distributed all along the lever to where the power is applied, affording' in effect a lever or"V the second order. Ot course, the cap screw or fulcrurn ineniber has to be properly adjusted for it' the set screw protrudes too 'tar it will be impossible to clamp down the opposite end ot the lid without bending the lever. On the other hand, if thecapscrew or fulcrum point is adjusted too far in, then there will be no clamping action at all at the left hand side of the elliptical opening. ln short, the fulcruin point has to be properly located so that all points on the riin are substantially in the plane of the packing ring of the lid at one point of its swinging arc. Of course, absolute precision is not required for the cork packing ring acts as a compensating factor, permitting a certain yield and indentation or' the rim.

lt will, therefore, be apparent that the packing' ring performs not only the useful and broader way of speaking of the lever action which has the point of power application where the wing nut engages the lid, the fulcrum, where the cap screw engages the clip and the load, allv along the packing ring.

lt will be noticed that the rim flange fr is of varying height to compensate for the curvature of the cylinder' and produce an upper edge which is in a single plane. This permits the flange e to be fiat. l have found that with a curved rim iange and a curved contact surface for the cover that one cannot get very effective clamping action.

ANhat Icl'aim is:

` 1. The combination of a container having an open-ing enclosed by a rim, a clip sup port-ed adjacent the rim, a detachable lid provided on one side with an integral ear interposed through said clip, an adjustable cap screw and lock nut screwing into the ear, and meansV for clamping down the opposite side of the lid, said means re-acting through the engagement of the screw with Y the clip to cause vthe'lid to bear firmly against lthe rim all along the same.

2. The combination of a container provided with aV rim and an opening enclosed thereby, a clip supported adjacent the rim, a detachable lid provided with an ear at one side provided with radjustable fulcrum means adapted to bear under the clip, and clamping meansfat the opposite side of the rim for clamping down the lid, said clamping means re-acting through the said fulcrum means and' the clip to force the lid ontothe riiny all along the same, and anintegral'reinforcing rib connecting said clamping means with the ear 'to transmit the power stress thereto.

3. The combination of a. container profvided with a rim and an opening enclosed by thesame, a detachable lid provided at one end with an ear, a clip supported adjacent the rim through which theV ear is adapted to be passed, the said lear being provided with `adjustable .fulcrum means to engage the clip, a second integral bifurcated ear. on the opposite end ofthellid, and a clamping member that can be swung up into the slot in the bifurcated portion yand forced down thereupon to hold the one end of the lid down `upon the rim and which stress re-acts through the opposite ear and the clip to press the lid down at both ends.

4t. The combination ofl a co-ntainer'prof vided with a rim and an opening enclosed thereby, a clip supported on one end of the container, a detachable lid having an ear provided with an adjustablefulcrum member adapted to be engaged under the clip, a second'ear at the opposite side of the lid having a bifurcation, a rib connecting the two ears, and a clamping member adapted to be swung up in the slot of the second ear to force the one end of the lid to the rim and re-acting through the first ear fulcrum member and the Vclipy to force the lid down against the rim all along the same.

5. The combination` of va container providedV with a rim and an opening venclosed thereby, a clip supported along the rim, a lid provided with an ear having a fulcrum member and adapted to Vbe hooked. under the clip and'at the opposite end with a second bifurcated ear, and a T-bolt pivoted' adjacent said bifurcated ear and adapted to be swung up into the slot, and a nut turned down againstV such ear to force one end of the lid against the rimand reacting through the adjustable fulcrum member at the opposite side 'to force the opposite side of the ear against the rim.

6.
